    • An adhesive dispensing system (10) and method are configured to melt adhesive on demand and maintain the adhesive in a liquid state between dispensing cycles. The dispensing system includes a dispensing applicator (14) including a manifold (30) with a manifold passage (34), a receiving device (12) including a receiving chamber (54) for holding a small amount of solid adhesive at the dispensing applicator and a first heating device (16) for melting the adhesive on demand, and a second heating device (18) at the manifold to maintain the temperature of the melted adhesive before dispensing. The receiving device is positioned adjacent to or partially nested within a manifold of the dispensing applicator such that the melted adhesive is delivered directly into the dispensing applicator. The second heating device applies heat energy to maintain the adhesive in the manifold passage as a liquid.
    • 的粘合剂分配系统(10)和方法被配置成按需热熔粘合剂,并保持分配循环之间处于液体状态的粘合剂。 所述分配系统包括分配施加器(14),其包括歧管(30)的歧管通道(34),接收装置(12)包括用于在分配涂覆保持固体粘合剂少量和一个接收室(54) 的第一加热装置(16)用于熔化按需粘合剂,并且在歧管中的第二加热装置(18),以在分配之前保持熔融的粘接剂的温度。 该接收装置定位成邻近或部分地嵌套检查分配涂覆的歧管内并熔融的粘合剂直接输送到分配涂覆。 第二加热装置施加热能以保持在歧管通道作为液体粘合剂。
